Solve the following absolute value equation for the unknown. Show all of your work for full credit. |-3h – 6| ≤ 3

ss7ja [257]

Answer:

$-3 \le h \le 1$ .

Step-by-step explanation:

Apply the property of absolute values: if $a \ge 0$ , then $|x| \le a \iff -a \le x \le a$ . By this property, $|- 3\, h - 6 | \le 3$ is equivalent to $-3 \le -3\, h - 6\le 3$ . That's the same as saying that $-3\, h - 6 \ge -3$ and $-3\, h - 6 \le 3$ .

Add $6$ to both sides of both inequalities:

$-3\, h \ge 3$ and $-3\, h \le 9$ .

Divide both sides of both inequalities by $(-3)$ . Note that because $-3 < 0$ , dividing both sides of an equality by this number will flip the direction of the inequality sign.

$-3\, h \ge 3$ would become $h \le -1$ .
$-3\, h \le 9$ would become $h \ge -3$ .

Both inequalities are supposed to be true. Combining the two inequalities to obtain:

$-3 \le h \le 1$ .

V. Money Magazine reported that the average price of gasoline in the United States during the first quarter of 2008 was $3.46. A

Butoxors [25]

Answer:

$z=\frac{3.43 -3.46}{\frac{0.15}{\sqrt{30}}} = -1.095$

$z=\frac{3.49 -3.46}{\frac{0.15}{\sqrt{30}}} = 1.095$

And we can find this probability using the normal standard table and we got:

$P(-1.095$

Step-by-step explanation:

Let X the random variable that represent the price of a population, and for this case we know the distribution for X is given by:

$X \sim N(3.46,0.15)$

Where $\mu=3.46$ and $\sigma=0.15$

And for this case we want to find the following probability:

$P(3.43 \leq \bar X \leq 3.49)$

And we can use the z score formula given by:

$z=\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

If we find the z score for the limits we got:

$z=\frac{3.43 -3.46}{\frac{0.15}{\sqrt{30}}} = -1.095$

$z=\frac{3.49 -3.46}{\frac{0.15}{\sqrt{30}}} = 1.095$

And we can find this probability using the normal standard table and we got:

$P(-1.095$
